1. A driving apparatus of a display panel, comprising: a clock controller configured to control a polarity inversion mode of displaying an image on the display panel; a switching power supply configured to supply power to the clock controller; and a temperature detection module electrically connected to the clock controller and configured to detect a temperature of the switching power supply and compare the detected temperature of the switching power supply with a preset temperature value, and when the detected temperature of the switching power supply is larger than or equal to the preset temperature value, transmit a first control signal to the clock controller; wherein the clock controller is further configured to receive the first control signal, and switch the polarity inversion mode of displaying the image on the display panel from a first polarity inversion mode to a second polarity inversion mode according to the received first control signal, wherein a power consumption of the switching power supply in the second polarity inversion mode is smaller than a power consumption of the switching power supply in the first polarity inversion mode; wherein the temperature detection module comprises: a thermistor configured to detect the temperature of the switching power supply; a resistor unit; a P type transistor; an N type transistor; a first voltage input terminal; a second voltage input terminal; a third voltage input terminal; a fourth voltage input terminal; and a control signal output terminal connected to the clock controller; wherein, a first terminal of the thermistor is connected to the first voltage input terminal, a second terminal of the thermistor is connected to a first terminal of the resistor unit, a gate electrode of the P type transistor and a gate electrode of the N type transistor respectively; and a second terminal of the resistor unit is connected to the second voltage input terminal; and a source electrode of the N type transistor is connected to the third voltage input terminal, a drain electrode of the N type transistor is connected to the control signal output terminal and a drain electrode of the P type transistor; and a source electrode of the P type transistor is connected to the fourth voltage input terminal; and wherein, when the temperature of the switching power supply detected by the thermistor is larger than or equal to the preset temperature value, a resistance value of the thermistor is larger than or equal to a preset resistance value, and then the control signal output terminal outputs a first control signal; and when the temperature of the switching power supply detected by the thermistor is smaller than the preset temperature value, the resistance value of the thermistor is smaller than the preset resistance value, and then the control signal output terminal outputs a second control signal so as to switch the polarity inversion mode of displaying the image on the display panel from the second polarity inversion mode to the first polarity inversion mode.

2

2. The driving apparatus according to claim 1 , wherein the temperature detection module is further configured to transmit a second control signal to the clock controller when the detected temperature of the switching power supply is smaller than the preset temperature value; and the clock controller is further configured to receive the second control signal, and enable the polarity inversion mode of displaying the image on the display panel to be the first polarity inversion mode.

3

3. The driving apparatus according to claim 2 , wherein the clock controller is further configured to: determine whether the polarity inversion mode of displaying the image on the display panel is the first polarity inversion mode when receiving the second control signal; and if so, maintain the polarity inversion mode of the display image to be the first polarity inversion mode; otherwise, switch the polarity inversion mode of the display image to the first polarity inversion mode.

4

4. The driving apparatus according to claim 1 , wherein the temperature detection module is integrated with the switching power supply.

5

5. The driving apparatus according to claim 1 , wherein there is a voltage difference between the first voltage input terminal and the second voltage input terminal, and there is a voltage difference between the third voltage input terminal and the fourth voltage input terminal.

6

6. The driving apparatus according to claim 5 , wherein the second voltage input terminal and/or the third voltage input terminal is connected to the ground.

7

7. The driving apparatus according to claim 5 , wherein the first voltage input terminal and/or the fourth voltage input terminal is connected to the ground.

8

8. A display apparatus, comprising a display panel and the driving apparatus of the display panel according to claim 1 .

9

9. The display apparatus according to claim 8 , wherein the display panel is a liquid crystal display panel or an organic electroluminescent display panel.
